Problems solved by technology
After the reflected sunlight directly enters the thermal imaging lens, it will cause a pseudo-high temperature area (also called a reflection point) in the thermal imaging image formed by the thermal imaging lens. The imaging grayscale value of the reflection point is much higher than that of the reflection The grayscale value of the image corresponding to the actual temperature of the object represented by the point, which seriously affects the accuracy of temperature measurement and high temperature alarm

The embodiments of the present application provide a data processing method and device, the method includes: detecting a thermal imaging image to obtain a high-temperature target; determining an imaging area of the high-temperature target in the thermal imaging image in a visible light image; determining the excessive temperature in the imaging area Exposure area; if the proportion of the overexposed area in the imaging area is greater than the preset proportion threshold, the processing operation corresponding to the reflective point is performed on the high temperature target. In this way, the temperature measurement error and high temperature false alarm caused by mistaking the reflective point as the heat source point can be effectively avoided, thereby improving the accuracy of the temperature measurement and the high temperature alarm.
Description
technical field [0001] The present application relates to the technical field of infrared thermal imaging, and in particular, to a data processing method and device. Background technique [0002] The sun's infrared radiation energy is extremely strong, and the sunlight reflected by objects with a smooth surface and high reflectivity still has extremely high energy. After the reflected sunlight directly enters the thermal imaging lens, it will cause a pseudo-high temperature area (also known as a reflection point) in the thermal imaging image imaged by the thermal imaging lens. The imaging grayscale value of the reflection point is much higher than the reflection point. The imaging grayscale value corresponding to the actual temperature of the object represented by the point seriously affects the accuracy of temperature measurement and high temperature alarm. SUMMARY OF THE INVENTION [0003] The purpose of the embodiments of the present application is to provide a data pr...
